going through the plant problem section and was trying to match up my plant problem.

this problem didnt start hapening till they got some good heat stress from 90degree temperatures for about 7 hours

i was looking at the heat stress pictures but these seemed to be a bit more developed

i was also thinking nute burning but its not effecting the tips at all

plants are in flowing stage at 12/12 untill they show sex. then i was going to get them back to vegging as they will be my mothers. plants get light from two 42 watt cfls. they are watered with ph rain water ~6.8, and every other time i have a gallon of water mixed with a teaspoon of mg.

This isn't zinc toxicity, it's zinc deficiency.

2-3 tbs/gal molasses every watering will fix this.

thanks for the reply but it seems im loosing in the game of plant life

plants were healthy then this morning after their 12 hour light bath they were droopy as hell. i havnt watered them in a while so its not that. only thing that i could think of is heat stress... sadly i had my thermometer in my vegging case so i couldnt record temps. next time im out getting molasses(which is what im hoping will stop the yellowing) ill get another thermometer.

edit: its not underwatering as the finger test still feels moist

That's due to N toxicity, most noticeble in the small one (much too dark leaves). It's because of the soil, it has time release nutes...

You need to transplant into a different soil or water much less, since the nutes in the soil are released each time you water.

thanks for the reply. i went over the back of the MG bag and somehow its not the miracle grow violet stuff(wtf indeed). its just the miracle grow seed starting soil. and itself says to replace into different potting soil after the plant has grown a few inches

hmm somehow this


got swapped out to be this
