hey bud lookin good....so how close are your light's.......

iron or nitrogen deficiency is the first that comes to mind....have you been checking the runoff ph and ec/ppm?

TLBWP

Probably a magnesium deficiency. I would suggest doing a foliar spray of 1 tsp. epsoms salts to 1 liter of water. Once a day for 2 days and then wait a few days to see how it responds. Also add epsom salts to your next feed. If your using city water that contains chlorine, make sure you let it site for a day first or bubble it to get the chlorine out. Chlorine can inhibit the uptake of magnesium.

Also, 20-20-20 isn't the correct nutrients to be using on flowering plants. You need something with less N, like a 5-10-10.

heya GoAuto and lil boy ...light distance is 10-12 inches from canopy, i dont think is due to light though (cz my other plants same height havent shown any sign of this kind yet) if its nitrogen def (i hope it is) she ll b ok after 3-4 days cz i already added, if its iron def ill add some next watering...thnx for ur help guys soooo appreciated...

im working on it muddy...that was her last feed with that NPK...im searching for something close to that u mentioned...i think its magnesium def also...ive already fed her today a Ltr with a tsp of epsom salts today, do u still suggest of foliar spraying the following 2 days and again a tsp on her next feed?? thnx

Look for orchid nutrients, they are very close to what weed likes and will usually grow a good plant. Also get something for your next grow for vegetative growth, something like a 10-5-5. They need the higher N for veg. Yes, do the epsom salts as I suggested, both the foliar and the next feed.

Unless you're using a cool tube, 10-12" is pretty close for a 600 watt light. While I don't see any signs of heat stress on your plants, I'd suggest you check it. Place your hand at the plant tops, palm down, and hold it there for 30-60 seconds. If it feels too warm on the back of your hand, it's too warm for the plants.

this is something i cant do in the summer only in the winter cz i have a big window right next to my closet that helps to bring the temps down - my hps actually works as a heater for my girls also....thnx again for ur help sir...

I had something similar with my girls, leaves yellowing just like yours but also some leaves very dark green. After reading the self diagnose thread I concluded it must be N overdose causing other elements to lock out. I use canna coco nutrients, don't have epsoms or anything else I could easily access. so I didn't know how to fix it, and I thought and I thought, and then it strikes me what if I give pk 13/14? That doesn't have much N. So I gave them a flush and then a bit of PK 13-14 and in 2 days everything was back to normal.

 

[yellowgrower]

i wish i could get my hands on one of those PKs 13-14...maybe ill give it a good flush and then introduce some flowering nutes....thnx for the info dildano :thumbs:
