Not sure what's up with my plants...

They have all been getting the same feeding pattern. Plants on the outside of the canvas are doing great. No problems at all. I have 20 plants in 3 gallon pots setup in a Sea of Green. What the deal!? Thanks in advance!

What are you growing in and what do you water with? Without details, it's hard to say. I have seen cal/mag issues do that, the plant needs more nitrogen under the light of something like that. Cal/mag issues disrupt the movement of nitrogen.

I'm growing them in soil.. its a mix of fafard pro potting mix, standard potting soil and mushroom compost. Also about 30% percent per perlite added. I used iguana juice during the veg weeks. Currently in the week 2 of flower. Week 1 I gave them water only coming out of veg and yesterday I gave them AN bigbud 40ml, voodoo 10ml, and sea crop 10ml. This dosage is mixed into a 5 gal bottle... This problem did not start showing on the leaves until i entered the flowering stage. I'm using two 800 watt led lights which are about 15 to 18 inches above the plants and the temps are around 78 F - 40 humidity. \\ Cheers!

ph?

ph is stable around 6.8

How big are those plants? Are the root bound?

They are about two feet tall after the grow spurt entering flower... nope. the roots should have enough space to breathe and take up nutrients throughout flower.. I've grown 3 ft plants in pots this same size outdoor and never had any problems.. they were also closer to being root bound and needed watering every two days.. these i water every 5 days..

Only for 4 of the 20 plants are showing these deficiences

Are the 4 a diff strain then the others?

i no you said PH was stable ,i think you need to recheck it and the runoff ,

They are all the same strain..

Have you done anything to anger Poseidon recently. Could be gods wrath or a deficiency of some sort

that is no deficiency , cut back the nuts , thats nutrient burn , your probably lucky that strain are handeling it well , some genetics at that stage would already be severely damaged.

Since its only 4 plants, it might be root rot. Maybe overwatering? How do you water? By hand or do you have some kind of system?
