re: Jon705's Multi Strain HPS LED Hybrid System
Dammit! I had a big response all typed up with quotes from several pages back, then it got lost. Grrr
Sorry I've been absent Jon. I missed the problems you had. It looks like you chose a plan of action and went with it. Sounds like it may work out for you. The plants look like they fit in there fine, but then I reminded myself they had not stretched yet.
What I typed, and lost, was I think this IS related to the RO. I have real bad tap water (450+ ppm). I get scale buildup within weeks of installing new fixtures in this house! At some point I'll install a whole house system to deal with that, but I don't want the traditional method of adding salt. In the meantime, I got an RO system for the basement.
The particulates in most hard water are predominantly Ca salts (mostly CO3 I think). Too much Ca can cause lockouts of P and Mg. If I recall correctly, your symptoms matched a P or MG def (or am I confused with another journal? lol). Adding the Epsom may have helped with the Mg, but it didn't address the high levels of Ca. IMHO, you should stick with the RO, but you seem committed to moving to soil. I'm not sure how important RO is with soil, but I'm a hydro guy.
A few pages back, you were talking about your ph with the RO. You mentioned that you were adding the same amount of ph down without checking first and it was pushing your ph too low. Before I switched to RO, I had to add a lot of ph down to get my res where I wanted it. After RO, I don't have to add any. My GH Flora, and I suspect most quality nutes, mix up right at 5.9. The nutes also contain ph buffers to try and maintain the ph. Your well water also contains compounds that are "buffering" the ph as well. That's why it took so much ph down with your well water.
With my RO, the ph of the water didn't change at all from tap. RO comes out just barely above 7, and my tap is ~7.1-7.2. The big difference is how strongly the water wants to stay there. With my tap water, it took quite a bit of ph down to get the mix down to 5.4 (since it would drift up, I mix it low). The first time I made nutes with RO, I did the same as you. I added the same amount of ph down and it went way too low. Then I got to go back and forth trying to get it back where I wanted it.
The point I was trying to make about ph and RO is this. Since there is far less 'stuff' in RO, it will not hold any ph well by itself. There is nothing to buffer ph, so tiny amounts of ph up and down can have large effects. Always add small amounts. You can always add more, but you can't remove extra
One last thing. Did I understand that you ph your water first?!?!?! That's a no no. I'm pretty sure every nute manufacturer says to ph last. This is specifically due to the ph buffers most nutes have in them. If you ph first, you're just 'using up' those buffers.
OK. One more last thing. DM Zone says to add it to the res first. I read all my labels almost everytime. Granted, that's mostly because I smoke so much pot and can't remember anything for shit, but it also serves to remind me which order to mix. I add Zone first, then the calmag and enzymes. I add my nutes last. I also mix my nutes in 5g buckets, then pour those into the larger res full of water. I mix them in 3-4 pieces, ie Zone goes directly into the res, Calmag and Hygrozyme go into first bucket, Micro, Gro, and Bloom go into the next bucket. FloraBlend and Liquid Kool Bloom (during flower) go into the last bucket. I'll also add superthrive up through stretch.
That's a bummer you had to remove plants. That's a tough call, but it's best to just move on. I'm sure it will all work out for you. Hopefully this summer will still be productive enough for you to swing the shop this fall.
Hmm...buds bigger than the plants can support...thats not a bad problem to have bro I have the epson salts because theres not really much mag in cal mag so its just incase
Thanks Mcloadie im kinda worried worried about using RO water now...I ll add some ca/mag and epson salts to the mix just incase, these girls are alot bigger and hopefully can handle change better than the small girls that were in the system.
after about an hr the plants looked a little shocked, some of them drooped but this morning it looked like they were recovering, I hosed them down good with insecticided and then brought them into a totally different enviroment, its cooler in there than outside and obviously the light source is totally different and the co2 levels are double so I was expecting some shock, we'll see in about 3 hrs when the lights come on how bad the shock is, I think they will be fine.The only problem I forsee is they are too tall for the room, Im pretty sure theres at least 1 probably 2 male BD in there, once I confirm that and get them out there will be more room to spread them out and tie them down, hopefully thats enough
