deficiency or over feeding?

[Freezy]

Hello this is my first post so I want to just say whats up and thanks ahead of time for any input. I have done a ton of reading over the past 3 years and this is my first soil grow. The last grow I did was a hydro DWC and it went okay but given my circumstances I wanted to try soil. These are bag seeds but I believe the strain is purple sour.

Soil: FFOF and organic 707
nutes: general organics
grown from seed
4x8 tent
1000w MH for veg
1000w HPS for flowering
rh averages about 35-40 flowering
currently at week 5 flowering
temp ranges from 60F-80F
5 gallon pots


So what I think is going on is lockout. I don't have a soil ph tester but I tested the runoff with strips about two weeks ago and they were reading pretty acidic (a ph of around 5). I think this was a result of me over feeding. I had fed at about 1/4 to 1/2 strength for the majority of feeding and according to the general organics chart. I began to notice yellowing, neurotic spots, and twisting and curling as it got worse. It started around the 3rd and a half week and I fed one or two feedings of full strength. When I did this it got worse so I stopped and flushed 5-6 gallons through the buckets. That was about a week ago today and this friday will be the 42nd day of flowering (beginning of week 6). Since the flush I have only watered them with straight distilled water. Should I start feeding again? any help would be awesome thanks. oh and one is in a 2x2 scrog and the other one is not. Just a little experiment. They are the same strain. Ive pulled a bunch of fan leaves that have basically wanted to fall off themselves and left the ones I can. I think there is probably about 4 weeks or so until harvest so I'm not sure what to do.

Thanks!

Re: Whats wrong with my plants?

Looks like they could use some Nitrogen

That late in flower I wouldn't add MUCH nitrogen, it could cause major foxtailing. Strange problem though, from the leaves it looks like their about done but the pistols say no. And it's starting from the top so I would say you need cal-mag. I'd add some Epsom salt or get some calimagic

This is the only one that looks this bad but maybe this will help tell.

Thank both of you for the input. I suspected cal/mag but I don't think it is only because cal/mag was the only nute that i was adding at just about full strength before I decided to flush. Does anyone suspect that they did/do have lockout? like i said i already flushed a bit over a week ago and now I'm just debating weather or no I should start adding nutes again or wait longer. If I add nutes what strength should I go at? 1/4 strength?

That looks light bleached.... I'd say it may be too late for that. Lack of magnesium can aid in bleaching. Magnesium is like sunscreen for chlorophyll. No sunscreen and intense light will destroy chlorophyll.

I would start feeding again at half strength because it looks like it got some ways to go. I had the same lock out problem but mines looked like calcium with CalMag and leaves begin to burn n shrivel. Only fan leaves new growth was ok. I flushed but I'm in week 8 day 1 tomorrow so I can't go back to nutes.

Okay cool I actually fed them half strength today so I guess we'll see what happens. Thanks for everyones input I appreciate it.

R they drinking lots of watered or slowed down?

They have been drinking about a gallon every three to four days days or so and the pots are not bone dry. The soil does drain but it retains a lot of water. Im going to use a different soil next time around. I have not checked the soil since yesterday when I watered them.. They are in the dark now ill check in the am to see how the soil looks and get back to you.

 

[2clean]

Try this. Half gal every two days. That's how I do it. I tried the 3 day thing and honestly watering two days less amount is way much better. I will noticed faster growth especial after 48 hrs.

 

[2clean]

They grow as the soul gets dryer. For example. I water and 24 hrs I look n noticed no difference then as it dries for next 24 U will notice that's when it starts to grow.

Yeah I'm noticing a little more growth out of the buds but the leaves are staying about the same as I figured they would. I don't know how long this strain takes in flower but this picture is day 45 of flowering or week 6 day 3. I figure ill chop them around week 8... What do you think?Btw happy 420!
