What is wrong with this leaf?

dexorated · #1 (**permalink**) 01-26-2007, 02:52 AM

I'm using fox farms ocean forest, 4th week of flower under a 400 watt hps. It's happening on the upper leaves, but not at the very top. Is it some kind of deficiency?

what is your runoff(soil) ph? Have u given it ferts? If so, how much? What are the temps at the tops of the plant? We need a little more info, and im sure someone who knows more than me will be here soon to help out.

PH is about 7 but it's hard to tell with the drop test... I'm getting a digital soon. Temps are 80 during the light, 60 during the dark. Been using fox farms big bloom fert

Temps are a bit cold at night. This could be the cause. The diagnosis however is vague; some kind of MICRO nutrient deficiency. I would start by giving it 1/2 tsp of epsom salt per gallon of water. This will rule out magnesium. Tell me, does the FF bloom ferts have micronutrients in them?

Sorry I forgot to mention that I had be using superhume/seaweed micronutes. I havn't used them for the past few waterings because I was leveling out my ph. Sounds like I need to give them a full does of the superhume next watering.

when u get the meter correct the soil ph to 6.4-6.8, and raise the temps to 65-70 at night, this will reduce stretch as well.
