Whats happening to my bud

I am think its my lights burning it but its spreading.
Its my first grow so i am a bit jumpy, i dont want to lose it now.

Ps i have moved my light up now 2 be sure.

the second pic looks burnt but i'm not sure about the 1st. someone with a little more diagnostic experience could help perhaps? it definetely looks like a defeciency or lock-up of some kind. what's the soil ph, nutes, watering frequency, temps, etc. the more details you give the better.

Well i am not sure about ph as i have not tested the whole grow. I know this isn't the best idea but it has been healthy for many months so far. I intend on getting a ph testing kit for my next grow. The nutes are canna terra and the soil is mirical grow. The temps vairy from 15 deg C and 30 deg C. I water when they are dry down to about an inch. The only main differance i am doing @ the moment is starting to weaken the nutes as it is comming the the end of it life.

What nute % are you using?
Are you dropping water on the leaves?

its about half strength now and no i dont leaf feed just water the soil untill some drains out of the bottom.

could it be chronic overwatering? if the soil is only dry to 1inch before watering that is a possibility. although it might look a bit different than the chronic overwatering pics i've seen on og. i can't remember exactly. where is it at in it's life cycle?

Its almost there mabe a week or 2 more.

i just reread your last post, i'm thinkin ph problems causing various nute lock-outs. if you've never tested the ph then you don't even know what the ph of the nute solution you're watering with. to avoid ph problems, i use 1-2 tsp dolimitic lime per gall of soil and i also adjust the ph of water and nutes to the low 6's before giving anything to the plants. you also should let your pots dry out almost completely before watering. overwatering could also be a problem. i'm just trying to think of possibilities for you to look into.
