Used ozone gen for first time had it on 15 mins off for 45 mins for 8 hours. As soon as lights came on I went in to check them and SPEWING!! the plant area immediately around the generator is curled under, leaves are limp and just not happy looking, although still green, but it has only been 48 hours since I did this damage and I am expecting it to go brown. Is the whole plant stuffed or will the visibly unaffected area still go on as usual. Needless to say I have thrown the generator and stick to the carbon filter. I have sprayed the affected area with water and super thrive, does anyone know what I can expect to happen now, will whole plant die, should I prune affected…

Lights to grow room containing plants vegging ( nearly ready to bloom) and mother plant was switched off on Monday 5.00 p.m. and not turned on til Wednesday 11.00 a.m. that's darkness of 36 hours.

Anybody know what this is? It's causing white spots on my leaves as it's assumingly feeding on it. It looks like some type of larvae, but thats all ive found so far. They're very tiny - thinner than a pin and not even 1mm long so i had to get my microscope to see what they were. Their bodies are whitish but quite transparent and look similar to a grain of rice under the microscope. They have black eyes which stand out against their transparent body, and two feelers on their head. Im not sure how many legs theyve got. Ill take my plants outdoors tomorrow and hose them off with water to reduce their population and then probably use pyrethrum to take care of the rest un…

Hey all, theres afew BB clones that have just gone into veg under a 400w hps. They were cut off an already purple stemmed plant in the hope the new clone would come good, but it hasnt gone green again yet. The leaves are slowly turning yellowing and with a few necrosis spots popping up here and there on afew fan leaves, also theyre looking kinda flimsy. Now theres been nothing new done to this batch that havent had good results in the past, using the same proccess and mediums/ferts. BTW, Im growing in a soil/perlite mix if that helps. Now i just wanted to know if theres any specific products that will fix whatever is wrong with them? So far ive narowwed it down to a…

I'm growing in Coco. 6 weeks in Veg. COGr Nutes. ph=5.8. Plants are generally healthy, really green with plenty of new growth. I'm a bit concerened because some of the OLDER leaves are showing signs similar to nute deficiancy. They are turning brown and crumbly on the edges. It's only on the leaves that were from the original mother plants when I took clones. What am I doing wrong?. Should I be worried?
