sproutco - Thanks. I've received such great advice from several threads, as well as some learning from reading more. I'll be trying this ASAP, this afternoon.

whiteflies can mess some leafs up! But can mess with the nugS!

Im on my first grow, and I was lucky enough to get an O.G. kush plant. Unfortunately the time frame for picking up the plant fell on the same weekend I was gonna be out of town, so my financial backer and connect to the plant had to set it all up himself, though he knows far less than even I do. The plant was infested with spider mites when he got it, so I directed him to 1tokeovertheline's mite irradicator

He didn't thoroughly read the directions, so he didn't cover the rockwool with plastic and it was absorbed by the roots. On top of this, 4-6 inches of roots were stuffed into the 1"x1"x1" hole on the top of the 4" rockwool cube and it was put in a 1200+ ppm solution without having soaked the rockwool overnight in ph adjusted water.

Needless to say, the plant was very unhappy looking when I got back in town. The first thing I did was dilute the nutrient solution to 7-800, then I soaked new rockwool cube in pH 5 water overnight, made the 1" hole on the top about 2 inches deeper, broke the rockwool I cut out into little chunks, and then transplanted the plant into the new cubes, using the rockwool chunks to surround the roots. Several days later it looked like this.

At first growth and recovery was slow, and it looked like it was barely hanging in there. About a week in I switched to the Lucas formula and from 24/7 to 20/4 added some GH subculture, and it seemed like
growth increased, but a lot of the new growth was very yellow.

Maybe this was due to letting the pH drift up to 6.5 and lowering the pH too much to 5, but since I was changing so many things at once, I thought I would go back the the original 3:2:1 GH grow/micro/bloom formula between 7-800 ppm, make sure the pH stayed between 5.5-6, and add cannazyme and scrap the subculture, which was beginning to smell a bit foul. I also cut off about 8 of the severely damaged leaves. Several days later it looked like this

There is a lot of new growth everywhere, but it is still yellowish. Here's a closeup

I'm thinking its an iron deficiency, but then again, what do I know? Any suggestions or ideas would be greatly appreciated. We're running a 600HPS in an a/c modified hydrohut with temps between 70-75, flooding every 7 hrs during the lit period, and with a 10 hr gap when the lights go off for 4 hrs. So I'm basically feeding 3 times daily. Obviously we are running too big a setup for this one plant, but hopefully soon this plant will populate the tent. Thanks in advance!

Help Me can i save her

asianko - Give some specs. Whats your medium, light, temps, water ph, nutes etc.

asianko, yes but not in the way you are thinking. If it was mine, and I wanted to keep it around, I'd take a cutting and re-veg that and then re-start the flowering process from a healthy plant.

My mother room is becoming infesed with very tiny black bugs on the bottom of the leaves a few are white maybe 10%. They are definately leafsuckers and the first bomb did not do the trick, I'm not certain what kind of bomb it was it looked like the pyretherum bomb but was alittle taller and 1/3rd the price @ 8.00 USD. What are they and what will kill them?

Sensi Star, I'm growing in a soil mix, Promix BH, amended with bat guano, mushroom compost, blood meal, bone meal, dolomite lime... Been using this mix for some time, no problems. 2000 wats. H.P.S., Temps. 77 to 80 degrees F., Humid. 42 to 46%,CO2 1500 ppm. I have no idea what is causing this leaf discoloration. I'm in week4 of bloom. Please advise! Allways,on Berryhill

I'm about 4 weeks into 12/12 light cycle of this hyrdo project. Supposedly PH is 6.5 and tds levels are 1350. I don't trust either the test meters or the tester. overall temps are in the mid 70's. The picts are top & bottom of a leaf.


Next pict are of some seedlings I have in a 50/50 peat & perlite medium


this next pict is a closeup of that one yellow leaf.


Any Op's based on what little info and low quality picts would be appreciated.

I have four healthy femaleplants under 400hps in soil, feed them with bio nova's pk (no nitrogen) and sometimes little amounts of vegferts to keep them green; probably already gave them their last nitrogen meal.. is that good or bad?? they've been flowering for umm maybe two weeks or so. Maybe i got myself a nutelock problem or sumthing. I give them once or twice a week PK, and according to the bottle i should be going with a 2 weekers amount, still somehow my greediness makes me give them the amount of a 3 weeker. I'll check the milligrams when I get home. Also, how do i increase the amount of resin? Actually i can't currently see any resin at all. Temps 27-29 celsius. Some lower leaves are turning yellow and dropping every day one by one. This is not bothering me, because i think it's just because the lower branches are getting energy to stretch further from the fanleaves. And the same lower fanleaves are getting barely light at all. So that's not concerning me.. But





Here's a closeup, sick flowering cola:



What do you think, is it bad or not? And yes, i know the fact that they've stretched like hell!

Also, I'm a bit frustrated because im moving at the end of next month. Will my gals mature on time?

Sorry to bother you all
