bubbler scrog setup
cyco nutes + cyco swell
nutes did get low a few times on 30 degC days
apollos were added 4 weeks ago
day 73 from 12 12 switch
should i flush for few days then harvest?

look at the gland heads, clear, milky or amber. What you got going on is a serious manganese deficiency/burn. Not a huge problem, but most likely caused by high salts. At day 73 into flower I would say you are close to harvest and you should flush for the remainder. Those leaves are very green and with the periods of high salt, your plants have lots of fertilizer in them and if you don't flush then your bud will smoke nasty and actually be harmful to you. Not medical quality at all, which completely contradicts what the medical movement is all about. Consider a clearing agent...clearex, final flush, ect... In the past I have flushed with straight Ro+Di with a little molasses to futhur sweeten the flowers.

the damaged leaves have f*ck all gland heads but the rest is looking close to 5% amber. only just chaged nutes today but i will replace with phed water. should have asked about the prob a few weeks ago when it started but i had too much faith in her lol. dont think i will have any clearing agents in reach as i am far from my hydro shop . thx tikitoker

how much molasses do you add

5% amber......don't bother trying to correct anything. It's my opinion that it's harvest time for you.

De-foliate that bitch, we want to lessen the mount of storage sites(fan leaves) leave on all trim( even burnt, it adds to the bubble heap) then flush with clearing agent for 24 hrs( despite the recommendations on bottle) change out clearing agent, then flush again for 3 days with 2.5 tbsp./gallon of molasses or anything you want that's all natural. At this point in time we dont give a flying shit about the roots (unless you will re-veg, then disreguard any molasses and shorten flush agent durration to remove excess bloom fertz, then dose for veg) so we can put in anything technically. 1 last pointer I think is always important. Durring all periods of flush, end stage de-foliation and carb loading, I like to SWTCH out HPS with MH, I use both 10k or 20k for a shit ton of UVB/UVA. It packs on serious crystals. Then I let her sit in the dark for 72 hrs, turn MH back on and cut her down within the first 1.5hrs.

sorry I forgot you said you don't have access to a clearing agent. Purified h20 will work fine. Also some say It helps to have some fertz in the flush water, just a little say 100ppm. Im not really sure why, it didn't make sense to me. Water with a value of 0 is able to dissolve more and hold more than water with a starting value. Water is an excellent solvent, one of the best.

had to make do with tap water, gave it a trim all over and flushed for 24hrs and have reflushed with water and molasses.
didnt realise there were so many more budsites bellow the trim should have trimed earlier.
thinking about harvesting the tall ones and letting the rest go for another week?

Damn son, looks like some good shit.
