i think i may have given them a bit of nute burn if you can see on the pic it is quite yelow on the tip of the leaves i can only see this problem on 1 fan leaf tho so i maybe wrong but any info would help? shud i just feed water next time to be on the safe side? also so im seeing on lower branches that some fan leaves are completley yelow and browning should i just cut these off, i herd somewher that cutting some of the bottom leaves of was good for circulation of air and concentrating more of the plants energy on the top budz.
