People of 420 I'm aware this one is very difficult to diagnose... (at least for me) but after 24 hours of reading I'm more confused now than before I started and feel a fresh look on this might help...
So the set up is as follows super silver haze in week 7 of veg, (I know long veg time but once I get them healthy and about to switch something crops up, not an easy strain)
Water ph 8 but after nutes added I bring it down to 6.7-6.8
water left out for 24 hours before every watering
Soil grown, house and garden special batmix
using house and garden soil a&b nutes*
been using Magne-cal also
400W hps
18/6 lights on/off
Temps during day 26-28 deg cel, night time no lower than 18 deg cel
*I have recently read that I should not use soil a&b with medium that contains lime... The bat mix has lime in it. Though its been flushed now a couple of times.
So the problem is in 2 of the 4 plants I have in the tent and they are yellowing/lime greening of the leaves starting from the outside and working inwards. Seems to have started half way up the plant spreading to the newer growth. Old growth seems ok at this point. The colour doesn't seem drastic at this point but im hoping ive caught this early, its getting worse.
Affected leaves feel almost crispy and dry.
Affected leaves have long skinny elongated tips which are pale in colour, some are twisting.
I flushed last night and the final 5 litres I added a half mix of nutes as at the time I thought it was nitrogen def. Now im not so sure, if it was nitrogen it would be the bottom leaves affected right?
My latest thought is manganese but ive been supplementing with magne-cal. as I say the more I read the more im confusing myself, here are the pics,
Help save my mental health at the same time...
peace
