I have some white widow plants that were doing fine and then i gave them a weak foliar feeding of miracle grow and they for the most part stopped growing verticle. they continued to fill a bit but its been about 10 days and still only verticle about an inch. they are now about 12-14 in tall, real green and healthy looking but not growing.

How do I save these plants 600wt lights Cocoa / perlite mix and Floating roots watertable. GH flouro RO Filter 69 t0 78 degrees Ph 5.8 to 6.4 Plants get thriving and kikn butt. About a month into bud when everything looks awesome they begin to mimic Mg deficiency. The brand of nutes don’t seem to matter. The more nutes I have the longer it takes to develop the problem, but now my nutes are at the peak i can give em while the problem grows.

I can see the light thru the spots. Soon i'll be able to…

Hey stoners I'm currently half way through the second week of flowering in a cabinet grow. I'm using a 600w lumatek digital with SonT globe with the booster switch on, and cooltube with inline fan to control heat. cyco flower A+B, Zyme, Rhizo, and Potash with EC about 1.7 and ph 5.6 growing in rockwool. Grow space is about 1m cubed Ever since I upgraded to the 600w (had a 400w magnetic before), the new growth on the tops of the plants that are directly under the light are growing yellow leaves. The first week I had the 600w I didn't have a fan connected to the cooltube, and thats when the yellowing started, but has been continuing even with the fan on…

Hey, hopefully someone can help!! Two plants about 4 weeks since transplant, under 600w hps, fully auto thermostat controlling exhaust fan, normal fan circulating air. Temp kept between 26 - 30 degrees celcius. growing in coco medium with a little perlite added to it, 12L pots. Not a hydro system but using hygro fert, does this matter?? Plant growth is great, very fast, sturdy and bushy. Still in veg stage. Bottom leaves going yellow, slightly drooping and curling at the tips, new growth is fine. yellowing starts between the veins, tips curl, then leaves die from tip of leaves and outer edges. end up having to cut them off. Thought it was magnesium so I dissolved some ep…
