Hi everyone, I'm just after some help.

I have 2 Humboldt Dream girls on day 21 on flower in canna terra pro. Feeding green planet dual fuel 1&2 at 1.5ml/ L
Light is mars fc3000 at 21inch from the tallest top @ 75% giving me 700 ppf.
always ph my input between 6.2 - 6.5.

I've had all these yellow tips throughout the plant slowly browning. Haven't fed in 2 weeks so I'm unsure what's happening if anyone could help me please.

Lights on temps are 78f with 60%rh

Herbal ive come to respect and value your input. Let me see if im following your logic; the tips are N related and that becomes less important as the plant moves into flower making the slight yellow not so important? Am i close? I have been trying to study the leaves in the pics and make a prediction on what the trustworthy comments suggest and in this instance i was way off from your suggestion. Thats the only reason i ask.

i have never seen leaves tips like that get any worse , just a slight nutrients imbalance, nothing i'd personnally worry about, that won't waste or have a signifiant impact with your harvest.

no it's just i had tips like that many time depending strains and phenotypes within a strain and that i have never seen it getting worse or impacting a signifiant way the final result and harvest, so i just don't bother.

Alright. I appreciate your response and has cleared my mind. I'm on my third round and have learnt different plants can handle different nutrient levels. I was only worried because every leaf throughout the plant had the same issue

Would it be safe to say to resume feeding?

yeah i d personnaly would continue feeding normally.

and yeah not all plants react the same to feeding, more or less capricious phenotypes are a thing once in a while

yeah 2.9 sound like it was a bit high here a chart i found when looking for recommended EC in soil:

Bbs ppm ec


as for how much you feed after a possible lockout i think i have read once that you should feed slightly lower that the EC you aim for, but not sure at all.

try google it.

That chart is awesome. Yeah I have spent hours scrolling the Web. Everything flushing & ec related is coco. I'll up it 1.6 if I'm aiming for 1.8

Plants look great. I’ve been wearing Chuck Taylor’s for years, good job!

Increase air circulation? Try going lighter on nutes from here on out and then see if it gets worse or stays stable?.

Looks like minor light stress, I would ignore it personally. Some of my best runs have minor tip burn throughout flower
