Sick plant?

[Mattylucas]

This is an autoflower 25 days old from sprout. I just noticed some of the leaf tips turning colour. I have two of them. Both doing the same thing. Under two "600" watt led lights. Actual watts is 100 watts for each light. I've just got my ph kit two waterings ago and have been putting the water at 6.5. I've only fed them root farm base nutes and veg nutes at 1/4 strength once. I didn't ph that feeding. Some one else suggested it might be over watering? I only water once every two days and the first inch is dry.

it's multiple issues. stay put- peeps will come. i can't... ph, definitely necessary, EVERY FEED ... measuring the 20% runoff, only... ain't about 2"; you'll get gnats n rot. watch closely... feel their weights, dry n fed... wait for em to shrug, on dry day n you'll know how they should feel, when dry. 2" in 2 days .. anyone think he needs to mix in some poop to use the moisture, more effectively/efficiently; in short?

yeah, I'm out. sorry.
