Hey Guys! Need some wisdom!

3rd grow
Soil (Miracle Grow Potting Soil) - 3 gal pots
600w HPS
White Widow, AK-48, and Bubblicious
beginning 3rd week of flowering

Foliage fed some miracle grow blooming fert about 1 week ago as per label to get the girls started down the right path (I thought). Then this lil guy curled up like a sob. Is this nute burn? And if it is why didn't all the other ladies go up in smoke? Also, if it is nute burn, what can I do about it in a soil medium? Finally, why did only the top leaves burn up? Commence the teaching!

The entire plant looks stressed though? manganese tox can cause cupping like that along with high ambient temps coupled with low humidity, different strains have different tolerance and even some of the same strains can have torally different tolerances.

Thanks SPLFreak! ...Just the top leaves are stressed. Temp never gets above 83 at the tops of plants and humidity is between 45-65. Is there anything I can do for this guy?

I would definitely stay away from the Miracle Grow in the future. It's just not made for cannabis. As far as what you can do now, I'm just not sure.

Im gonna go ahead and say toxicity issues. If temps are 83 at the top that must mean the room is in the high 70's?. Anyways i used to use mg potting. Yea you can use it and yes you can get to harvest but i have never ever had to add any extra NPK. I only had minor calcium deficiencies throughout the grow.

Ya.. the box (5x5x6) stays pretty much between 74-80. You guys got any suggestions for what I could be adding in additional to the nutrients already in the potting soil that will help the girls with their blooms and not burn them out? Or do I just let this time released soil do its thing?

From my little bit of MG experience. Im gonna say you only add nutes when she ask for it. Minor deficiencies is a whole lot better then minor toxicities.

You said you foliar feed (spayed with solution) if so you should only do like 1/4-1/3 the strength you would do for a soil drench when using a base nutrient. Like stated diff plants have diff tolerances so that could be the cause or maybe the plant just got sprayed more then the others. Don't spray they plants anymore either now that you 3 weeks into flower it could cause mold. As for nutrients you don't need any right now just water they are really dark green and have plenty of nutrients
