It's classic Phosphorous deficiency... But why? Everything looks correct...in your list. They don't look very green... Are you feeding them enough? Double your nutes and see what happens. Double check your Ph too...
Thanks for the response. Looking at pictures of deficiency's I was leaning towards phospherous as the issue, and agree with you, but I am not sure the best way to correct it. Should I just add another nute to my solution thats higher in phospherous? Is 330ppm too low? I have some tiger bloom that is higher in phospherous but would I really want to add that while they are in veg state? Any and all advice is much appreciated!
Ok, thanks for the reply. Where abouts should my ppm's be for this stage? Im really trying to dial these girls in. They were doing awesome and then they just started to crash.
just wanted to say thanks for those that helped me out and give everyone a quick little update. For hose who said my girls were under fed, they were right on the money. Alot of people kept telling me it was nute burn, so I was keeping the ppm's low. I decided to go the other way and take the advice of those that were saying I wasnt feeding enough. Man, what a difference. My girls have completely turned around in the last few weeks. All the new growth looks spectacular....roots, stems, leaves.....totally looking sweet! So thanks to EVERYONE for their advice and replys!
Excellent! Glad to hear I could help. I really need to grow for a living... it comes so naturally and its SO much better than my 9-5
