Ive enclosed some pictures.

Hey, beaver. I'm finding it a bit difficult to tell, but if I'm seeing right, I'm seeing a combination of different possible issue such as heat stress, nute deficiency (N and possibly magnesium) light-stress and I think under or overwatering.

Do you happen to know what your environmental conditions are? Temps/humidity watering/feeding schedule etc?

its an underwatering im sure of that i got a lil drunk thursday night and missed a feeding.

2 grotek prosilicate
10 grotek vitamax plus
10 botanicare cal mag plus
16 jungle juice bloom
8 jungle juice micro
/ gallon is what im feeding them

i realized a little heat stress as well and raised the light humidity has been a little low at 38 and temps are normal at about 77.

Hey beav. That looks like a mag deficiency for sure. Yellowing between the veins. Get some epsom salt and put about a tsp or two in a Gal of ph water and give them a feeding. You could also do a foliar feeding with that solution for a couple days and it should turn around. Spray the tops and bottoms of leaves right when lights are about about to cut out or with enough time before cutting on to soak up good. You don't wanna have the lights on them when they're soaked from the spray. Good luck.

Hmm.. I'm guessing here.. but my gut feeling says it's environmentally related. All those things combined can cause symptoms that look exactly like lockouts and it's easy to think it is one.

As I say though I can't say with 100% certainty.. just experience of seeing very similar leaf markings when my environment was out-of-whack.

You know the girls better than anyone.. what does your gut (not your head) tell you about the issue?

Seems to be a variety of deficiencies. The first thing that comes in my mind, check ph. Next, over-fertilization; it can cause multiple elements' lock-outs.

Beaver, did you try the link on your wall?

 

[beavergoods]

which link eschatos. im pretty sure everything started when i bought my new fan i think it was on a lil strong thats when i noticed things started and it happened closer to the fan and where the fan would hit. my ph sits at 5.8. I dont think im overfeeding im basically giving them a modified version of lucas with some vitamins and cal-mag and then some silicate for better absorption. This is a difficult one.

And, you are not giving them Grow. They need Grow nuts throughout their whole life, unlike Bloom.

Cut back a little on nutrients on the next feed, and add Grow in your feed mix.

As I said before, multiple symptoms suggest overfeeding or no balance in nutrients.

I hope you sort it out soon beaver, get them girls up and running
