What deficiencies am i battling?

[Waira]

--- main problem is the dry-outs, that will harm the roots, screw with pH and stress the plant out,...damaged roots don't work well, won't move nutes and water fast enough to deal with the low RH% and high T, which start to snow-ball the defc. symptoms (mostly P and N),... keep more consistent moisture levels, up the feeds a bit, and manage that T and RH% better,.... I know it's a PITA. but it's what needs to be fixed,...

Yep, environment bro. Do what you have to to get the environment under more control. Inkbird costs 25$ and keeps temps in line. Humidifier to keep RH levels good, and a little more time spent checking the soil moisture in this heat, and you are good to go. We all have to learn it. Once the environment is good, the plants will thrive.

Yeh i check the pots everyday, sometimes there dry in 2 days some times 3 days, rh stands about 35% during lights on sitting about 30c sometimes. When lights off rh rises to about 55% :/ thought it would be easier growing in the summer man, makes me feel like im just not good at this.

With this UK heat my fan is on full anyway all day. Even lights off temp sit steady at 25/26c. I can turn my light down to 250w then temps sit about 28/29c. Just that dam RH!

Don't worry. Summertime is tough growing indoors. That's usually when I take my break. I just finished, and I usually don't even like to go that deep into summer, but sometimes you have to do it. Hang in there. You will see as the temp go down, how much easier it I see to grow. You can always turn the heater on, but without air conditioning and good humidifiers, it's tough to grow in the heat.

They are still fine though. Post some more pics so we can help you with assessing what they need. It won't be long, you will have some bud, and then the next grow will go better in fall anyway. You will surprised in the end. You will have bud!

Get some buckets of water, and some wet towels and lay them around on the floor around the plants. That can really help them have some available moisture in the wire for the leaves. Hit them with some mist on the leaves whenever you can. Fight the heat back bro! It's just a battle. Hopefully this heat wave will calm down soon and you will have I think easier.

Thanks man! Makes me feel better there's people like you looking out for people like me!

Guess its just a teaching moment, wont be growing next summer! Sativas are loving it tho (stilton) strawberry nuggets not so much. I have a coolmist humidifier but was under the impression the RH should be around 35-40%?? I'll stick that back on while lights are on, just worrying when lights off it climbs to 55%. Ill be sticking pics up tonight after work, i can see mag deficiency (i think) so just calmaging every feed.

Look at this chart. It will tell you where your RH should be based on the temps you have. Stay in the safe zone and only go into the high transpiration zone in late flower for best results.

Take a look. It will really help you. 35 to 40 % is good if your temps are 17 or 18 degrees C. At 30C the green zone would be around 67% RH man. That's why your girls are suffering.

Take a look at the chart. Your 30C temps and 40% RH gives you a VPD of over 2...ouch not good for plants. In the red zone man

28/29C temps...RH should be around 65. At night with temps 25/26C...RH should be 60 or so, 55 is fine. Get that RH way up in the daytime when the lights are on and you will see new plants. 100% for sure guaranteed improvement!
