clones turning yellow HEEEEELPP!!!!!

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 rooted clones...the second is of the unrooted

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?

My clones looked like this and after a few feeding of a light dose of 'grow/veg.' nutes they bounced back..

bumpppppppppppppp

im not gonna read all that...im sure it says bascially what you did..

they look fine just feed them

lol yea sorry for the novel...but i jus put it all out there so i didnt get a bunch of standard questions

well to begin with ur really worried over nothing. the damage aint dat bad.

but here goes, cut back on the nutes, move your lights farther away or remove 1 bulb,

when the roots are small or nonexistant, bright light cuases too much photosythisis requireing uptake of nutes for that, on top of building a new root structure.
its like if u

im sorry imnot splanin this right, imkinda under da wedder. ill try later

buuuuuuuuuuuuuump

double bump

they look ok.

how old are they?

my clones looked like crap for a week, yellow leaves and droopyness. (i think maybe cutting the tips to avoid transpiration woulda help). at day 10 they sprung right up.

but i dont give any nutes. i mist with like you have ph 5.5 water and minimal ppm. mine are over 5 weeks and i still havent given them any nutes. less is more imo.

and what about the heat mat? your not using it? if its not drying out the rockwool, root growth is really promoted when their medium temp is 5-10 degrees that above ambient temp.

i like the set up tho i wanna have that many clones ready for this summer.

my attempts with the heat mat have been disasterous...i live in the south so its already hot as fuk already and its a lil difficult to keep my heat down as it is...in the past when i used it it completed stunted the growth and basically led to me having a 100% failure after weeks of anticipation...ive tried it twic after and had minimal success...the old fashion way takes longr but at least i know im garaunteed roots and im too frustrated to really try a heat mat again and have weeks of anticipation go down the drain
