Bump

from the start. I don’t think they’re rootbound because even some of the smaller plants are showing the same symptoms, the yellow leaves with green veins. This photo is just before their watering/feeding so it hasn’t had anything for 72 hours, hence a bit droopy

Hi guys, me again! so I’ve got these plants at day 21 of flower in 30L autopots that were being fed every 72 hours and I’ve started getting yellow leaves with green inner veins. They have very slight tip burn and the ec is 1.8 in the res so I’m not under feeding should I switch to a smaller...

I’ve decided to adjust the valves tonight so I’m giving them a bigger drink every 72 hours. If I still see the yellowing I’m going to drop the valves right down to the minimum and feed every 48 hours

yes I’ll give that a try. Thanks

I’ve just filled the res with the 3rd weeks flower feed so they’re not getting any nitrogen. This week they got an added PK booster but they aren’t showing any signs of coming round. I removed the deficient leaves yesterday and today there’s more dying off. Do you think I should keep it at 72...

Hi guys, I’ve got a couple of monster plants in 30L pots of soil. I have a timer on them to water every 72 hours and they’re not showing any signs of under watering but they are showing potassium deficiency. The pots flood for 15 mins every 72 hours so they’re getting enough feed, but I’m...

I’m every 3 days at 1.6ec but I’m guessing they’re going to drink a lot more now they’ve been flipped. Thanks for your help as always buddy!

So the nutrient company recommends 4ml per litre, I was already giving 5ml per litre and 2.5ml root stim… so I’m going to be at about 7.5ml per litre of just flower nutes? Thanks for your help, I’ll give it a go at 1.7 ish

Hi, my EC was 1.6 in veg, ive got some 5ft monsters but I was using 5ml per litre of grow and 2.5ml of root stimulator I’m not going to use the root stimulator through flower, should my EC in week 1 still be at 1.6 or can it be lower at say 1.3 without the root stim? im in 30L pots in soil...

Will give it a try. Thanks for your help everyone

the autopot guys say that’s a bad idea to water from the top once you’ve started watering from the bottom as salts can get stuck in the middle section. They recommend to flush from the bottom but with just ph’d water

Yeah thanks a lot. think I’ll give them a big flush and slowly bring it back up

i don’t have run off with them being bottom fed. Used this system for years so I don’t have to check on them too regularly

ill keep the ec at 1.3/1.4 and water less frequently?

Please bear in mind these are 30L pots so they’re quite some size. Would you say some of the drooping is overwatering? I’m wondering whether to keep the EC at 1.4 and feed every 72 hours instead

theyre bottom fed through an auto watering system which feeds from a res every 48 hours. They suck up most of the water/feed quite quickly. I’ll take some photos and reply here

Hi guys, I started feeding some plants about 8 weeks ago,they’re now currently huge bushy plants I started the ec off at 0.6 then 0.8 the week after im now at week 8ish in veg and at about 1.3ec and there’s some yellowing/brown crisping to some bottom leaves and the they’ve all gone quite...

It’s just a local soil from a garden centre but never had any problems with it before

Thanks guys. Great advice from you all
