Holy Grail Kush Problem

Looking for some assistance as I'm a bit stumped by this one, I have this HGK from DNA currently into day 34 of flower, but she's just refusing to put any weight on the buds, and is showing some signs of 'burning' on the tips, along with clawed leaves. However, the leaves remain very light (lightest in the tent) and not what I'd expect from an N-Tox.

I've been feeding it the same as the rest of the tent, the rest of which are doing better for sure. 1ml of BioGrow with 3ml of BioBizz Bloom, and some bloom booster with some amino and fulvic acids once a week and an Alfalfa mulch which was placed down about a month ago. They were also all given some espom salts once in week 2. My waterings are done with RO water at 6.2-6.5 pH and I use a coco based living soil with a variety of initial amendments (a popular brand here in South Africa).

My initial thought was K lockout from a pH issue, but runoff is sitting at a happy 6.3

Any insight would be appreciated.

Im guessing too much water.

I only water when pots are weightless but with that said, it's not impossible as she does have some drainage issues, or she's just not thirsty but I water most the plans every second day and this one takes about 3 to dry

Interesting. Like you said resembles nitrogen toxicity but the leaves are pale. Still appears to be root issue from what you described above. Check for root aphids. Bottom of tray or pull from pot and inspect root ball before watering next.

day 34? from the flip to 12/12 or from seeing visible buds? The lack of weight could be strain dependent maybe its just too early?

Im not much for bottled nutrients so i cant help you there. I had a similar issue with my plant late in veg. leaves were getting pale with burnt tips. I topdressed with a handful of worm castings and made a compost tea and they have bounced back for the most part. notable growth spurt immediately
