Hey there Sukafr33, I have been trying to catch up with this grow and I'm at page 5 or so and I smoked a little and now I'm not so motivated to read but the last few pages your plants are looking very good dude, congrats. It only gets better. Everyone seems like they have you going in the right direction but I figured I could help you out with the techniflora nutes a little, I wished throughout my last grow (first grow) someone with any experience would chime in and let me know what was up with them, but I was sold on them as well with the RFS kit. The only things I would add were SM90 and hygrozyme to basically what the kit recommends.
A few things, its always best to apply the roots 66 alone seperate from any of the other nutes, I have no real information as to why but thats what the customer service suggested, only use with sugar daddy. Techniflora is a nute program that is intended for hydroponics but are acceptable for soil/soil-less use, they will produce perfect buds so dont think you have to switch until the next go round, theres no need, the more you change the more your plants are going to stress and bottom line is stress translates to more time before you are chopping buds down, so try to avoid it if you can. However, I would suggest getting a more soil or hydro specific nute for your next grow depending on what you are going to do. I just started running botanicare in my soil less, the way they are used translates easily from the techniflora line, liquid karma is like thrive alive red and a few others are very similar and basically the same type of products just different manufacturer with a little different mix, at least thats what it makes me think. Basically a complete nutrition program is what you get when you use the whole line (basically like all the other companies out there). Also, when you water or feed follow the PH instructions (seems like everyone else set you up with that info already), I think in most cases it calls for 6.1 or 6.2, stick with that and you'll be fine. But use the feed/water/water thing they suggested, if not you'll need to flush more often. Techniflora's RFS is meant to be used with either decent tap water or RO water (I am doing 50/50 ro/tap myself), I know I read that you were using spring water, I dont know if you still are or not, but I'd personally recommend against that, I hear nothing good about it, as long as you airate your water and theres no chlorine in it, you'll be ok unless you have a well, then I dont know what to say, go RO. Hydroponics is better suited to pure pure water I think, filtered/dechlorinated water is better for soil I think, at least so far anyhow. Either way though as I said, you look like you are on your way to a good harvest if you relax a little, its hard to not interact with them but trying to just let them be is the best thing you can do, also it takes days for something thats going on as far deficiencies to show in the leaves, so its going to take just as long for a remedy or a change thats going to fix it to take effect as well, just try one thing and give it 2-3 days before doing something else unless its a leaf eating virus or something...then you got bigger probs but you get the point.... as long as its not getting worse and as someone else said, if new growth looks good, your plants are growing and healthy. Most times as long as you arent over-watering, a good watering/flush and then letting them dry out good is going to fix it unless its a disease or parasite. Checking the PPM of the run off when you are plain watering will give you a good idea as to how much fertlizer is in your soil as well as long as you know whats going in, works for PH as well but be mindful of whats going in and you wont have to worry about whats coming out but it never hurts to check. If you see the new growth all burnt up and discolored, then start thinking about what needs to be changed in a hurry.
Aside from any of that with the techniflora stuff, dont believe the bullshit about not having to flush with their product or not flush often....flush often...., you need to flush and flush frequently as salt build up is a reality with those nutes (and basically all synthetic nutes to my understanding), they work great and produce great buds, just make sure you flush properly at least every 2 weeks give or take and at transitional points in the plants life, before flowering when you start feeding bloom nutes and then depending on how long flowering strain you have at least every 2-3 weeks depending on how heavy you feed. Buy stock in sugar daddy towards the end of flowering, its basically like a molasses/sweet/carbohydrate product that adds flavor in flowering and its expensive as hell, botanicare sweet is a good replacement as well as cheaper I think. They have flavored but I use the raw unflavored myself. And most importantly, do not follow the pre harvest routine, you want a minimum of a full week of flushing before harvest. If you are running a 9 week strain you want to do that pre harvest routine before the end of week 8 and then straight water or water and sugar daddy and thats it, just make sure you flush flush flush towards the end for that last week. I did all that and still had salt build up showing on the leaves but it was all good at that point, it was time to chop. Also, for the first week of flowering whatever the recommended dose of boost is stick with that and 50/50 grow/bloom + supplements after you do a pre flowering flush, 2nd feeding go with straight bloom sch.
I ended up with some really good bud (a few of my friends really like it, however I was a lot more critical of it, but it is really good knock down indica high) on top of a fairly decent yield on my first grow with the techniflora RFS, so if I can do it, it can be done by anyone. It is a decent product, but having used it, I say its a great way to start and makes feeding faily easy but there is much better products out there for soil that either cost as much, or are a bit cheaper. Not many are as easy to use as techniflora is though, so take advantage of the easy feed factor and learn about the plants and how they grow throughout their lives, dont worry so much about what brand of nutes you are feeding them and if they are organic or not. I hope in the future to grow using 100% organic soil and nutes but its worth learning with synthetic, organic is how you grow once you know how to grow efficiently, you will have plenty of time to refine your skills once you know how to give your plants what they need rather than what you think they want, if thats not the biggest lesson I learned up till now I dont know what is, that and dont even bother trying to rush anything, it aint happening... In the beginning being a new you need to much technical information and exact answers to try and formulate a recipe with organics, they make it easy buying bottles. There are some new organic products out there now though, I havent heard to much good about the organicare or general organics. All the companies will have one shortly though if not already.
Good luck, just relax a little, give your plants as much alone time as you can and you'll do fine.
