Thanx for replies guys. Also found a few yellowing leaves on bottom of plant. Any ideas?

i’ve been feeding 1/4 strength nutes and only gave them the first dose on day 22, then 2nd dose on day 27 and 3rd on day 33. could it still be too much of something?

Hi all Quick question, can anybody tell me what this is on the leaves? It has been very hot so found it hard to keep temps down, i’ve averaged about 34c last week. The top leaves were praying a bit so i’ve been moving lights up and getting the fans blowing a gale on the top canopy to try and...

cheers for the replies, i was being cautious and had them at around 28 so will move them down and see how it goes.

hi all i have the bestva 1200w LED lights on a 18/6 schedule and i can’t seem to wrap my head around how close i can get my lights to the top of my canopy. so my question is looking at spec how close can i get my lights in veg and then flower stages? (without giving them to many umols) thanx...

cheers bud, thats encouraging. it was all going beautifully to this issue popped up, and it’s def stunted growth but all trial and error

thx for all the reply’s. i will def start checking ph and hopefully see improvement. if it is the ph causing the problem and i have nute lockout, do i need to flush now? or will this hurt the organisms in the soil?

i only bought it because lots of ppl using biobizz seem to have magnesium prob start around 2-3rd is that common amongst newbs?

i have two 6 inch oscillating fans, passive intake with more than a good enough extraction fan causing negative pressure. prob is i got my tent in a cupboard under the stairs for stealth, and i can open door at certain times but the heat builds up.

lots of different opinions on the ph-ing with organic soil so i haven’t checked ph once. if i remember correctly i think the water in my area is around the 200ppm mark. i don’t let the water sit for 24 hours like some ppl do, is this a mistake?

ideally i would like the temp lower. temp was around 25/26c with just veg lights on but full spectrum raised it. i might have to buy AC to keep temps lower

around day 14 i started 1/4 strength nutes

i actually bought calmag today, does the same job as epsom salts? i am using 1200w LEDs. wouldn’t light burn effect top leaves closest to light? the top leaves are the least effected and i can’t really see any light burn but i have had consistent temps of around 30c-32c since turning on full...

hi all, so this is my first grow. i am growing in biobizz light mix soil while using biobizz nutrients. i am growing 3 autoflower plants and around day 30 i started to get some lower leaves turn yellow. after some reading and comparing pictures online i thought i might have a nitrogen...

hey all, first timer here. this auto is 3 days old, it is 1.4inches. does it look a bit skinny and leggy or i am just worrying too much. any help appreciated
