PS MAKE TEA NOT WAR !!!!!

First check your soil pH. Next, feed them a nutrient ratio close to 3-2-2, properly pH'd. Always wait for at least the top third of the soil to become bone dry before watering again.

thank u mothers finest do u still think its gunna b ok? wat is the problem is it just a nute diffency or have i shocked it badly during the transplant ? i have nute feeder witch is 7-7-7 ? is that ok to feed it with as i have said im completly new to this and trying to learn and recover frm my mistakes lol cheers man

PS MAKE TEA NOT WAR !!!!!

i have done a ph test and the soil in 6.5 , 7.0 the temp in the grow room is 80 ?

If the soil pH is ok, go straight to feeding. While we can't say much for certain about your fertilizer, it at least seems to have all three macronutrients. Give it a try.

They look fine to me, as for ph don't worry about it at this stage. Thats not ph causing this. Those leaves always go shitty. I never feed mine untill they are in there 3 gallon containers. Normally when they reach 6 inchs. Hope this helps. PS whats your watering schedule

cheers guys well my warteing schedule i dnt really have one i jus wait till i c the soil is dry then give them a good dose of warter then wait again till soil is dry ect ect i can see that its spreding to one of the other leaves now its here is an up to date pic i feed it nutes and i fear its made it worse im to sure wat to do

Give it until the soil dries again. Plants aren't as lively right after watering. It'll perk up.

Be sure to check the pH of your fertilizer solution when you feed them, unless you've checked it before and know what the pH of that particular mix is.
