clones turning yellow HEEEEELLLPPP!!!!

before i get any haters yes i have read through the archived posts but havnet really got an answer for the way i was taught to grow...

im growing sharks breath on an 18-6 schedule

i grow with rockwool with a t5 and my veg room is usually at 77 degrees its very difficult for me to get it lower than that...but RARELY over 80 (maybe if im out for a couple hours and forget to adjust the temp as the day gets hotter) with lows at maybe 70-72 when the light is off

my light is about two to 3 feet from the clones

ive been having problems cloning because im a relatively new grower and i was experimenting a little too soon with heating mats, overwatering and just general over-attentativeness...so this time i jus kinda cut the clones dipped them in phd water at 5.5 with a little superthrived and hygrozone and jus kinda let them do their own thing under a dome...

i cut clones using clonex and a clean scalpel...i was excited when i started seeing roots after a couple weeks so i took the dome off and transfered the smaller rockwool cuebes to 3 inch cubes and dipped them in a solution of flora micro, gro, and boom at 5 ml per gallon...shortly after that i started noticing yellowing and some even had brownish tips...my problem with what ive read is ive read this is overkill with the nutes...but ive also read that yellowing signifies nute deficiency...so dont really know which way to go? to reduce or increase nutes?...and a friend of mine has been doing this same method for years with no problem...ive had clones before and in addition to the yellow this batch they are growing very slowly....

i know a small amount of yellowing is ok because it signifies growth...the pics dont really do it justice they are slightly more yellow than new growths that i see on my mother....and it looks like the yellow is coming out of the growth instead of th bottom leaves...

the problem is happening now to both my rooted clones and my soon to be rooted

the first pic is of the unrooted clones...the second is of the rooted

please help!!!!!! i feel like weeks of anticipation are going to be wasted...what can i do to fix this????

and also what can i do to ensure it never happens again?

That's normal .. With about any strain.I think you'll be fine.:thumbsup: Nice set up.. The ones that are unrooted shoulda been trimmed back of some of the leaf blades. Look good though!

I've used rockwool and love it! Very versatile, with all sizes. Gotta keep it a little more simple on the rooting solution.Use something like olivia's clone solution.Soak the cubes after being ph'd to 5.5.All ya gotta do is spray with water,use a dome,and DON"T LET THEM GET COLD!

IMO, the reason your getting yellowing and burning on your rooted clones is nute burning the roots. Back off on the nutes like GaGrown kinda hinted at. ;)


Healthy roots = Healthy plants!


Happy growing! :weedpoke:
