My girls are almost 30 days old and they seem happy, but they have yellow tips. Can anybody help diagnose these from these pics? I'm using GH grow flora series at 2-3 tsp. a gal. and a little hygrozyme 8ml a gal. Cause my roots were turning brown (they're fine now). Is it a Ph prob. or nute burn? This is only my 2nd grow and my 1st aero grow. My first grow sucked. Help please.

I am leaning toward nute burn. flush your pots with water til they run clear. let you babies drink that water over a few days then start adding your nutes back at half or quarter normal for a week or so.

What is the temp at the canopy of your ladies?

the temp of the canopy has kinda varied lately, it was at 74-78, ive been doing cab upgrades, i have ac,and a chiller for the res so i started co2 and took the cab up to 86-88 and kept the res 66-69, i dont have a co2 moniter so im not sure of my co2 level, so im back to 75 intell im sure i have proper co2,

I would flush your tank with water for 24-48 hours and then run a new batch of nutes, looks like ya might have fed them too much too early.

this is all you need for c02, just remember if you run a carbon filter, dont run it all day cus that will mean you need to run co2 often, just run a few cycles daily and you will be good, besides the amount of co2 you need for that cab would be like .25 sqcf for 5 mins to get it up to 1500ppm

thanks morris ill start the flush today, i used the chart to set my correct rate of flow but with the ac on alot im not sure how much stays in the cab, ive purged a ton of stuff welding and know how easy it is to lose inert gas, ive seen some co2 moniter/contol for 320 on e bay, i can prob make it happen this tue. i even dropped my cab temp intell i get one. my girls are only 1ft tall right now, im not sure how long i should veg for?

they look great, if you have indica plants, which thats what they look like, they should double during flowering, so if you can only go 2ft tall, then flower at 1 ft, the plant will do most of its growing during the first 3 weeks of flowering then slow down to thicken out bud sites, check this link out Indoor Growing Systems

also the a/c only recirculates air within the grow room, so your not losing anything, just to make sure, everytime you open the doors you will lose, so maybe a co2 cycle should go on after you do some garden. the air being blown out the back of the a/c is the hot air that comes in on the side vents in the back of a/c, this has no bearing on cab side a/c
