Hello everyone, i have two plants two weeks into flower... a gelato 33 which is doing just fine!!! and a green ninja which has started showing some signs of a problem that I need some advice on please. the ninja’s leaves started to curl down at the tips which I noticed this morning...upon checking them tonight the leaves are completely curling down...I thought it could be one of two things, and thought peeps on here might be able to help me pretty please... basically my ph pen died yesterday! It won’t calibrate anymore so I think the readings are completely off! (I’ve ordered a new one and will be here by Sunday). This morning I had to reluctantly guestimate my water ph as my ninja was in desperate need of water...so I’m thinking incorrect water ph may be causing leaves to curl down.... OR... the plants a bushy beast! In a 3 gallon pot and I can see fair amount of roots underneath via the drainage holes...so thought it might possibly be root bound?? Temps are constantly 26-27 degrees Celsius with lights on....21.5-23 degrees Celsius lights off...with a tower fan and clip on fan moving air around so I don’t think it’s heat stress.... Advice massively appreciated!!!!!

Any help, direction etc very much appreciated... I have three clones, doing very nicely, though stuck in a small veg area while their mum flowers... I staggered taking the cuttings, so I can experiment to a degree - the first clone was potted from 0.5 to 1lt 3weeks ago and is becoming or is, root-bound. I do not have the option of potting up so plan to trim its roots and re-pot into 1lt. If it all goes to crap, I have a couple of weeks to work out what to do with the other two - worst case, one lives and is potted up. Can anyone advise on good practice for root trimming or direct me to any relevant threads, please? I have found a few discussions, though on hydro trimming, which isn't really helpful - I guess bonsai'ing a mother would be the closest to what I am trying to achieve, though temporarily. As I say, the aim/hope is to put these three in for a few additional weeks veg and turn them to 12/12 when mum comes out... Many thanks in advance.
